Answer:
Option a is correct.
The rotation for the transformation to △A'B'C' is , rotation of 90 degree.
Explanation:
In △ABC
The coordinate of point A = (1,1) , B = (3,1) and C = (1,4).
Rotate triangle ABC 90 degree's around the origin;
The rule for this transformation is:- (x,y) to (-y ,x)
A(1,1) to A' (-1,1) ,
B(3,1) to B'(-1 , 3) and
C(1,4) to C' (-4,1)
therefore, rotation of 90 degree counter clockwise rotation around the origin results in the transformation of △ABC to △A'B'C'
Answer:
The midpoint is ( 7,-6)
Step-by-step explanation:
To find the x coordinates of the midpoint, add the x values of the endpoints and divide by 2
( 6+8)/2 = 14/2 =7
To find the y coordinates of the midpoint, add the y values of the endpoints and divide by 2
( -3+-9)/2 = -12/2 =-6
The midpoint is ( 7,-6)
Answer:
r=0
Step-by-step explanation:
34r-12+8r=-12
Combine like terms
42r - 12 = -12
Add 12 to each side
42r-12+12 =-12+12
42r = 0
Divide each side by 42
42r/42=0/42
r =0
